Which Type of Carbon Nitride More Suits Photocatalysis: Amorphous or Crystalline?

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 10, 2024

Abstract Graphitic carbon nitride (g‐C 3 N 4 ) has witnessed tremendous research interest due to its narrow bandgap, intrinsic 2D structure, and abundant raw materials. Although g‐C some shortcomings such as low specific surface area, poor conductivity rapid charge carries recombination, various modification methods are constantly emerging enhance potential application value in photocatalysis. Increasing the crystallinity of is an effective strategy improve in‐plane separation efficiency. However, it also reported that amorphous possesses a higher adsorption activation ability over reactants richer functional groups than crystalline . Which type more suits photocatalysis, which method suitable for boosting activity two types , respectively? Based on these issues, recent advances preparation properties summarized, their performance improvement strategies overviewed thoroughly. Upon systematic comparison analysis, respectively, proposed. Their applications summed up especially environment remediation energy conversation. Finally, ongoing opportunities future challenges photocatalysis territory taken consideration.

Published: Jan. 12, 2025

In this research, S-scheme heterojunction photocatalysts are prepared through the hybridization of nitrogen-rich g-C3N5 with TiO2 (coded as TCN5-(x): x weight ratio TiO2:g-C3N5). The photocatalytic potential TCN5-(x) is evaluated against benzene (1–5 ppm) across varying humidity levels using a dynamic flow packed-bed reactor. Among composites, TCN5-(10) exhibits highest synergy between and at "x" 10%, showing superior best degradation performance (e.g., 93.9% removal efficiency, specific clean air delivery rate 1126.9 L g–1 h–1, kinetic reaction 46.1 nmol mg–1 min–1, quantum yield 6.0 × 10–4 molec. photon–1, space-time 1.2 photon–1 mg–1). formation an built-in internal electric field supported by both theoretical (through density functional theory calculations) photoelectrochemical bases improvement in band electrochemistry along surface characteristics reactive sites charge migrations interface)). results situ DRIFTS analysis confirm that oxidation molecules accompanied many intermediates phenolate, maleate, acetate, methylene). outcomes work will help us pursue development state-of-the-art system for quality management.
